Thermal Expansion

Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature. The coefficient of thermal expansion describes how the size of an object changes with […]

Thermal Conductivity

Thermal conductivity is the property of a material to conduct heat. In SI units, thermal conductivity is measured in watts per meter-kelvin (W/m·K). This Thermal Conductivity converter allows you to convert Btu (IT) inch/hour/sq. foot/°F […]

Thermal Resistance

Thermal resistance is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow. Thermal resistance is the reciprocal of thermal conductance. The SI units of […]

Heat Density

Heat Density, heat flux or thermal flux is the rate of heat energy transfer through a given surface per unit time. The SI derived unit of heat rate is joule per second (J/s), or watt […]

Heat Flux Density

Heat flux density is the heat rate per unit area. In SI units, heat flux density is measured in [W/m2]. Heat density is a scalar quantity, while heat flux is a vectorial quantity. This Heat […]

Heat Transfer Coefficient

The heat transfer coefficient, film coefficient or film effectiveness is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat (i.e., the temperature difference, ?T). It is used […]
